SmCo magnets

SmCo magnets , also called SmCo magnetic steel , one kind of Rare Earth Permanent materials , made from raw earth metal Samarium and cobalt, with iron , copper , zirconium, praseodymium and other metal elements in certain proportions , by melting , milling , shaping , sintering processes. Due to its excellent properties : higher magnetic properties (high energy product, high coercivity, high remanence);very low temperature coefficient (-0.030% / ℃), high working temperature (The maximum temperature is up to 350 ℃), negative temperature un-limitation, the good stability of the maximum energy  product-BH, temperature and chemical , strong anti-corrosion and oxidation resistance, now widely used in aerospace, defense industry, microwave devices, communications, medical equipment, instruments, wind power, avariety of magnetic drives, sensors, magnetic processor, high-end motor, etc.
SmCo1:5 magnet, also Called SmCo5.Made from the metallic samarium, cobalt , iron , copper , zirconium, PrNd and other metal elements in certain proportions , by melting , milling , shaping , sintering processes. The (BH) max range is from 16 to 25, maximum working temperature reaches 250°C.
The mechanical character and ductibility of SmCo5 is better than Sm2Co17, easier to be machined in to complex sizes ,very thin disc and thin-walled ring .
